Abstract (en)

[origin: US4875270A] A method and apparatus for securing one or more parts, each of which is provided with an opening, to a hollow member. In the starting state, the inner diameter of the opening of the parts is greater than the outer diameter of the surface provided on the hollow member for securing the part. The parts are placed in the prescribed position on the hollow member prior to the securing operation. In order in a simple and economical manner to reliably secure the parts to the hollow member without the danger of overstressing the latter, and without the danger that the parts will loosen, a temperature difference is produced, prior to placing the parts on the hollow member, by heating the parts and/or by cooling the hollow member. Subsequently, each part is secured to the hollow member by widening the latter at least in the securing regions thereof, and by a subsequent shrink fitting of the parts onto the hollow member as a consequence of the temperature equalization that occurs.
